R Session Aborts when running Python chunk

[aleccampanini]

I'm using Windows and RStudio aborts the session when I try to run a python chunk. I've tried pointing to the python executable in my anaconda folder using use_python.

Code Chunk 1

library(reticulate)
py_config()
use_python("C:/Users/S1855433/AppData/Local/CONTIN~1/ANACON~1/python.exe")

Output 1
python: C:\Users\S1855433\AppData\Local\CONTIN~1\ANACON~1\python.exe
libpython: C:/Users/S1855433/AppData/Local/CONTIN~1/ANACON~1/python37.dll
pythonhome: C:\Users\S1855433\AppData\Local\CONTIN~1\ANACON~1
version: 3.7.3 (default, Apr 24 2019, 15:29:51) [MSC v.1915 64 bit (AMD64)]
Architecture: 64bit
numpy: [NOT FOUND]

python versions found:
C:\Users\S1855433\AppData\Local\CONTIN~1\ANACON~1\python.exe
C:\Users\S1855433\AppData\Local\CONTIN~1\MINICO~1\python.exe

Then when I try to run my python chunk:
Code Chunk 2

import pandas as pd
import selenium as sn

The first error message that pops up is

The second is the message that says I should abort and restart my r session.

I've tried uninstalling anaconda and reinstalling but nothing has worked.

I had the same issue a time ago, I filed an issue on github, they told me to update reticulate to the development version and the error went away.

Python chunk fails to run in windows desktop version with error: This application failed to start because it could not find or load the Qt platform plugin "windows" in "".

Hey how would I install the development version? Currently I'm running version 1.13 for reticulate.
When I run install.packages("rstudio/reticulate") I get:

install.packages("rstudio/reticulate")
Installing package into ‘C:/Users/S1855433/Documents/R/win-library/3.5’

To install a package from Github, you cannot use install.packages.

You can use the install_github function in remotes package.

After installing remotes, run this: remotes::install_github("rstudio/reticulate")

[aleccampanini]

I tried that and got this error message. I redownloaded r tools and set it to my PATH and continue to get the same error message.

remotes::install_github("rstudio/reticulate")

UPDATE: Ignore my comment below. I missed that the poster mentioned installing Rtools.

@aleccampanini

Package reticulate has compiled code, but no suitable compiler(s) were found. Installation will likely fail.
Install Rtools and make sure it is in the PATH.

Have you installed Rtools? You'll need that to be able to compile the reticulate package on Windows (when you use install.packages(), it installs a pre-built binary version from CRAN that therefore does not require compilation).
